Six Oakland quarries

Oakland, like most growing cities, started its climb to prosperity with the resources it had on hand. Those were land, soil, water, timber and stone. Today we produce no domestic stone. Here are the remains of six different quarries, five in Oakland and one in Piedmont.

Sibley Regional Volcanic Reserve is a former quarry where the basalt of a Miocene volcano was exploited for traprock.

The Morcom Rose Garden is said to be a former quarry; that would have been a gravel pit given that there is no bedrock mapped there.

The Hiller Highlands neighborhood is built around an old quarry where the highly faulted rocks (the Hayward fault is just to the left of this photo) were handy for making crushed stone.

Part of the Serpentine Prairie was exploited for rock at some point, probably for fill material.

Piedmont’s Dracena Park is the former Blake quarry, yielding Franciscan sandstone for aggregate under Oakland’s streets.

And the Zion Lutheran church, off Park Avenue, was built in an old quarry where sandstone of the Franciscan Complex was dug for crushed rock.

There are more of these; I just need to sort through some more photos. I think it’s important to source raw materials like stone from nearby whenever possible.

Mary, I’ve featured that quarry a few times, most notably in this post, but I’ll try to post a portrait of it in the next batch. Christine, I featured that quarry in this post, and I have a new photo lined up. Bob, I don’t have a photo of that spot yet.

Jafafa, there’s not a lot around Oakland, but along the Silverado Trail in Napa you can pick up some excellent obsidian (see this piece from my collection).

Thanks!
I’ve recently moved back to the bay area from NY. Can’t drive due to disability, but can hike. Need to find some geology field trips to tag along on!

Quarries here are much different than in NY. In NY they’re dangerous places. One in the middle of urban Buffalo is the source of famous and rare eurypterid fossils that are in museums throughout the world.

Been meaning to thank you for this blog. I’ve always been fascinated by geology but it’s somewhat hard to self-educate without hands-on experience, especially with an 8th grade education like mine, and California geology is so different from the NY rocks I’m used to. Smells different!

Hopefully sometime in the next few weeks I get to show Peter Roopnarine of Cal. Academy of Sciences a spot in Pinole where I found an interesting fossil that he’s interested in exploring the source of.

(Though my interests are wide-ranging and varied, it always feels like everything comes down to geology at some level. Am I the only one that feels this way?)

Merritt College sits directly on quarry pits. As a kid we used to hike up there along the Leona trail. At the time we used to call the site “devils punchbowl”,of course to build the college the pits had to be backfilled.

ps. Stauffer Chemical Co had a Sulfur mine at Leona Park. Leona Lpgge is anchored into the opening of the mines entrance. I hiked around there in the 50s. I saw piles of sulfur outside the mines entrance as the house I lived in at 25 Berneves Ct was built in 1958. It was named after Bernard Neves, who lived a t the bottom
